MANUFACTURING 00., OF LANCASTER, PENNSYLVANIA, A CORPORATION OF PENN V SYLVANIA TOY DETONATOR Application filed October 23, 1931. Serial No; 570,721.

This invention relates to toys and'more particularly to a toy detonator adapted for the explosion of caps or similar explosive. devices. r

One of the objects of the invention is to 'providea device so constructed as to increase the intensity of the report of the explosion,

while at the same time rendering the effects of the explosion entirely safe. That is to say, the invention contemplates the provision of a hollow shell or casing having an anvil provided with a central opening communicating with the detonating chamber of the shell and an anvil formed at a downward angle around said openingso that when the tachably interlocked therewith in such a Way that it can be disconnected by proper manipulation, but under ordinary circumstances will not separate from the shell, thereby facilitating handling, and'at'the same time materially enhancing the value of the invention from a practical and manufacturing standpoint since it permits of properly connectingthe shell and anvil without the necessity of springs or other devices which necessarily complicate devices of this kind. v i

A further object of the invention is to provide a device wherein the hammer is substantially entirely concealed within the hollow shell or casing so that only the string to which the hammer is attached issues from the end of the shell opposite the hammer.

With. the above and other objects in View, which will more readily appear as the nature of the invention is better understood, the same consists in the novelconstruction and arrangement of parts hereinafter more. fully described; illustrated and claimed. I Y

Preferred and practical embodiments of the invention are shown in the accompanying drawings, in which 2- g Figure 1 is an elevation of the present improved toy.

Figure 6 is a vertical cross sectional view of the construction shown in Figure 5.

Similar reference characters designate cor responding parts throughout the several figures of the drawings.

The present invention includes inv its organization ahollow shell or casing designed generally asA and which may assume various shapesa-nd forms'so far as design is concerned and may be susceptible of a wide range of exterior ornamentation. In each instance", however, the shell A essentially comprises a hollow body having the wall or walls 1 enclosing a detonating chamber '2 provided at its upper end with an opening 3. This opening serves as an outlet or guide for amanipulating string S connected with a hammer device B which cooperates with the inclined anvil face t at the end ofthe shell opposite the opening 3. The anvil face d is preferably inclined downwardly and outwardly or, in otherwords, is of substantially frustoconical shape and communicates with the detonating chamber 2 through the opening 5 so that the exploded cap or cartridge will be discharged toward the ground or floor.

The hammer B preferably includes a head portion 6 and a shank 7 connected by an inclined anvilsurface 8. r This face cooperates with the anvil surface 4 on the detonating shell to initially receive and hold therebetween a cap orother explosive element due to the weight of the shell'l, and subsequently explode the same when the entire device including the shell A or hammer B are dropped to the ground or other surface by manipulating the string S. The inner end ortail portion of the hammer B is provided with the offset or outwardly extending fins 9 and 10, the former being, in the example shown, of substantially 'V-shaped cross section and the latter having the offset wings or equivalent elements 11 (Figure 4) so that the fin Cal will be wider than the fin 9. The purpose of this construction is to detachably lock or key the hammer B and shell A together. That is to say, the opening 5 in the body of the shell A is provided with a recess 9a whichis of the same shape as the fin 9 on the tail ofthe hammershanki7. WVhen it is desired to assemble the shell and the hammer, the latter is placed at such an angle that the enlarged finportion 10 n1ay fit in the opening 5 and-when the iin 9 having the same shape as the recess 9a registers therewith, the shank of the hammer may be inserted into *the chamber 2. A slight twist of the hammer or shell circumferentially will, of course,

.throw the/fin 9 outof register with the slot .90 soithatthe parts willbeheld against accidental separation.

. ,Another featureof the hammer B resides in offsettingathe end-of the hammer shank 7 asrindicated at s12 to:accommodate the string S. That is, the end of the shank-isperforated and ofl'setsothatthe end of the string S may be threaded throughthe perforation oreeye and knotted at the end, andthe body of the string will fit into thegroove 13 made .possibleby the offsetting, thereby to center the string axially with reference to thehammer. In use the shellA .is held in the hand and ince the hammer .B is loosely held interlocked with the shell,a cap-C may be readily ,placed zbetween .the anvil faces a-and 8. supporting-the device with the stringor cord S the weight of theshell A :wilL-of course, vbeiimposed on the hammer B and thus hold .thecap between the anvil surfaces. Upon permitting the entire device to drop while held-by the stringS, the force ofthe hollow body orshell A moving toward the anvil B when .the latter strikes theground or other surface will cause the cap to be exploded and, therefore, make a loud report. The intensity of the report is increased because of the hollow detonating chamberQ and also since .the force of theexplosion is directed downwardly the sound waves resulting from the explosion will strike the :ground which acts as .asounding board to cause thesaid-sound waves to more effectively rebound to further increase the intensity of the report.

Without further description it is thought that the features .and advantages of the invention will be readily. apparent to those skilled in the art, and it will of course be understood that-changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.

I claim: I 1.
